The Hisense 65U9N wins for its 3000 nits peak brightness and increased dimming zones that reduce blooming compared to the U7N's 2000 nits and fewer zones (per RTINGS and Tom's Hardware). The U7N remains competitive for gaming at a lower price point with identical 144 Hz refresh rate and HDMI 2.1 ports. Choose U9N if HDR performance matters most; U7N if budget is primary.
